Bioprinting technology makes it possible to not only fabricate 3-D freeform shape, but also precisely place various cell in a single structure. Many researchers have been giving an attention to the technology because the technology can produce 3D cellular constructs. However, the introduced printing technologies cannot produce a construct with substantial size and enough physical properties required for clinical application because the technology only permits the process of cell mixed hydrogels which has weak mechanical property. In addition, channel incorporation for nutrient and oxygen supply is not easy with the material. As such, new technology was developed, which is hybrid bioprinting. It concurrently delivers high strength polymer and bio-inks to overcome the current limitations. The printing system was constructed. Then the system was successfully applied into artificial tissue regenerations such as ear, bone, muscle, vasculature etc. |
